Research in Atomic physics is primarily focused on spin-polarized gases,
liquids, and solids, on their properties, interactions, and a wide range of
applications. Among applications currently being developed are searches
for violation of CP symmetry beyond the Standard Model,
tests of Lorentz invariance, development of miniature atomic clocks,
ultra-sensitive atomic magnetometers, and new biomedical techniques,
such as lung imaging and mapping of the magnetic fields generated by the brain.
Biological physics spans a huge range of subjects, from neurobiology to genomics to
fundamentals of protein action. Princeton has strengths in nearly all areas of modern
biological physics. Many faculty with a strong physics background who are involved in
biological physics are not solely in the Physics Department but have joint appointments
with other departments or are completely in other Departments.
There is a strong community spirit to biological physics amongst these departments in spite of the vast range of subjects being studied.
